################Notes from V 0.1 ###################
    #maybe issues with windows
    #this code may help
    #open_wrapper(os.path.dirname(bpy.data.filepath))
    #Could streamline code
    #(if you want to make your operator more modular you can also set it as a prop and use that in draw:
    #row.operator("findandopen.run",text ="Open Folder").directory = os.path.dirname(bpy.data.filepath)


################Notes For V 0.3  ###################
    # @melmass
    # Technically though it's not ideal that the os.path operation happens in draw,
    # but it was to give you the context of how to add prop to operators, it would be more efficient
    # in this case to keep it in execute so it's only run when you ask it and not every time it's on screen
